Never, there are to many solid and 'free' / low cost alternatives such as opnsense, sophos xg, etc. Between the alternatives and the bullshit from their idiot management / owner I'll never touch their products / software and push everyone I can away from them.
I think they may have shot themselves in the foot on this one. One of my friends is the lead network engineer at a midsized MSP, and after this fiasco they've already committed to never buying another netgate box or pfsense license again, they're evaluating opnsense and other appliances in the same cost range. They've also heard a few other MSP's they sometimes compete with are exploring alternatives as well. Time will tell how this plays out.
