Hopefully every developer who has the means to still drops Unity like a bad habit. They've tipped their hand and shown what they're willing to do, which is 'as much as we can possibly get away with'. It's only a matter of time until they find a new, more abusive way to do this. I think at this point, any developer who chooses to use Unity when other options are equally viable for their project is, to use Unity's CEO's own words, "a fucking idiot".
