The creators/venture capital funders got their payday and the MBA's are now in charge as the company must keep increasing profit every quarter...forever.
Anyone that trusts unity after this will get exactly what they deserve next time greed make unity put thier privates in a vice to squeeze out more profit with unreasonable terms then half backpeddle to less insane but still obviously unpopular changes.
It won't, but hopefully people looking to get into game development are more hesitant to pick Unity. If people aren't learning Unity in school or on personal time, the work force for it's going to shrink, and it'll eventually fade to nothing.
This doesn't even need to be a boycott. Just a negative suggestion will slowly wile away the numbers, as their engine fails to innovate, gets outpaced by competitors, and lives in the shadow of its former self, entirely thanks to Unity Technologies making the biggest PR disaster I've seen this month.
