The people in charge at Unity can’t just take over their customers project and boot the Devs out if they protest like Reddit did with Subreddits they protested for too long where they just banned the mods and took over the subs that had gone dark.
There’s way more control in the Devs hands in this instance but Unity seem to be trying to rely on the fact that it’s a massive pain in the ass to switch to a different engine mid development but that’s definitely not stopping some people from making the migration still.
