Someone who agreed to a prior version of the license will always be able to abide by that version of the license. The fact that they removed the provision going forward is just them trying to lock-in future customers.

No, it was a plan to lock in current customers that didn't look into license every time they updated engine.

That's why they removed the repo too, too easy to see the changes.

Whatever, a plan to lock in anyone who accidentally "agrees" to the new terms. You know what I meant.

I just wanted to highlight it wasn't for just new customers like you wrote but potentially every game in development using Unity. That's a massive difference.
