I would imagine Australia is covered by the Netflix deal.

Nope - the second sentence says:

The global streamer has picked up the animated kids series Star Trek: Prodigy for the U.S. and most international territories in a deal with CBS Studios.

And this is from the footer of this, more recent, article:

Additionally, the animated children’s series, Star Trek: Prodigy, is coming soon to Netflix and in Canada on CTV.ca and the CTV App, and is currently available on SkyShowtime in the Nordics, the Netherlands, Portugal, Spain, and Central and Eastern Europe.

If you're in Canada, it's important to note that it won't be on Netflix here - instead, it will supposedly be available on ctv.ca and the CTV App, but not Crave as far as I'm aware.

Bombardier has argued that its alternative — currently a prototype — would offer a cheaper and more high-tech aircraft that’s made in Canada.

Aye, and if my mother had wheels, she'd be a wagon.

They announced it back in October.

Meyer summarized the situation at Star Trek Day 2022:

“Alex Kurtzman made an interesting suggestion to me. He said, ‘I wonder what happened during those 15 years’ that Khan was marooned or exiled or transplanted, take your pick, to Ceti Alpha V, which was at the time of flourishing planet. I thought that was a really cool idea. I wound up writing three one-hour episodes for a Star Trek television show that for reasons beyond Alex or my control hasn’t been made until now. So it’s going to be a podcast. It’s going to start life as a podcast. I will take those scripts, adapt them, expand them, and as with all writing, get a chance to make them better. So I hope you’ll all tune in for them.”

I’d personally completely forgotten about the river of time stuff and the intention to never emerge.

I freely admit that this probably falls under the category of "personal interpretation" - here's the exchange that makes me think that (without identifying who's speaking, because the site I found doesn't provide that info):

Instead of fighting time, we go with it.

Stop trying to destroy the Sphere.

Merge it into the river of time.

Send it so far into the future, it can't do us any harm? I collected sensor data from Dr. Burnham when she first arrived.

The Red Angel suit has almost limitless quantum computational power. Literally infinite storage.

Meaning you can transfer the Sphere archive into the suit, program a destination beyond Dr. Burnham's anchor point and let the wormhole take it forever? Perpetual infinity.

Control will never get the data in order to evolve.

However, I don't think this idea is ever really acknowledged after this conversation, and like you said, Burnham seems thrilled when she arrives in the future in season 3, so maybe I'm way off.

Was the sphere sentient by that point?

By that point, the sphere was actively resisting attempts to tamper with it or delete or destroy it, though it doesn't appear to have developed a personality.

They couldn’t just destroy Discovery?

They tried, in "Such Sweet Sorrow" - the sphere disabled the auto-destruct and raised shields, preventing the Enterprise from firing at Discovery.

Or spore drive the ship far away?

I believe they discussed this as a possibility in "Perpetual Infinity" - IIRC, their conclusion was that it was too risky to bring the sphere data anywhere, which was why their original plan was to "merge it into the river of time" (which, to me, suggests they never actually intended to leave the wormhole.

I don't personally think the climax of season 2 is very good or clearly-written, but there are explanations provided for a number of things.

do you honestly remember why Discovery had to go into the future and be “erased"

It was to ensure there was no way for Control (which they were not certain had been eliminated) or anyone else to get hold of the sentient sphere data in their possession. I admit the episodes are a little muddled, but it seemed like the original "Perpetual Infinity" plan had been to go into the wormhole and never emerge, which isn't exactly what happened in the end.

and even if you do … does it feel like a good or interesting story point to you?

Absolutely, I think the 32nd Century is pretty great, and the time jump was the means to that end.

There are allowances for genetic therapies to treat medical conditions, but this probably falls outside of that realm just a bit.

Spock flat-out said it at the end of "Such Sweet Sorrow, Part 2", albeit with a focus on the time travel shenanigans of the second season:

Regulation 157, Section 3 requires Starfleet officers to abstain from participating in historical events. Any residual trace or knowledge of Discovery’s data, or the time suit, offers a foothold for those who might not see how critical, how deeply critical, that directive is.

Therefore, to insure the Federation never finds itself facing the same danger, all officers remaining with knowledge of these events must be ordered never to speak of Discovery, its spore drive, or her crew again, under penalty of treason.

Q did it? Seems fine
