this seems a well-argued article
to me the 'General directionless development' seems the most concerning point, I don't think the 'let's go with what the community ask\want' model is gonna work in the end.
I agree that it would be nice to have a "solid" roadmap to see what is planned for the future. It's not easy to put up actual goals and implement them in a FOSS project but that is something that the core team might be able to do. In the past there were only blog posts about the general ideas for the upcoming releases (i think 4.1 was supposed to be mainly stability improvements and bugfixes after the big 4.0 release).
dunno where you've been the last 5 years, but being a unity dev has been far from certain. dots, pipelines, ugui, fragmentation of runtimes, it's been ridiculous.
FOSS has less to do for or nae than my belief that Unity has screwed the pooch in a way that destroys trust. going after past products and asserting they can charge per install?
GET FUCKED
any partner you work with that tries that shit you need to lose immediately - that's a real, valid and true threat to your business man.
I think you need to step back and get some perspective on how violently unity fucked themselves with this shit show.
