I bought it blind on gog when it was on sale, visual novels aren't my thing usually, but it did not have the anime look so I thought I gave it a try and drop it after half an hour.
Turns out it was one of the most impressive games I played these last years. What a mindfuck!
And the ending warmed my cold heart!
So I wanted to watch a review on YouTube, and what! The! Fuck! I had no idea how different (and gruesome) this game could get! Soon it's holiday time, and it's on my top list of things to do! Let's see how I can fuck things up!
I only use Gog, and the good thing is, as you wrote, I CAN take my stuff and just leave, not that I would have any reason to at the moment.
Well, I do have other accounts like Steam and Ubisoft, but that's only about ten games in total. Stopped buying there a long time ago when I realised I can't backup my purchases and have to use their platforms to play.
I do miss out on many AAA titles, but seriously, they don't appeal to me anymore. And I can wait until they drop on gog eventually.
But I don't really see the problem in multiple accounts. If not owning is not a problem for someone why should he/she care?
