While you can make this argument about literally anything, it seems apt to make it about a multi-billion dollar company chasing a trillion dollar company.

It's fine to support them while they are the underdog and are saying and doing the right thing, but don't pretend like they will say and do the right thing forever.

I don't think the parent was ever saying they'll be good forever. More that if they do become evil, their licensing lets you continue using a revenue structure that made sense at the time you chose it (even if new versions have super awful terms).

> Who cares what the motivation is if it gives real benefits to devs.

Motivations matter, because they will decide in which direction a project moves over time, or if situations change. Epic is the "good guy" now, but only because they are an underdog. If they become the dominator, they might become the predator which Unity tries to be at the moment.

But if we are honest, such uncertain possibilities don't matter if they are so far in the future. This might be a problem for future games, 10, 20 years down the river..
