This is of course not including the yearly Unity subscription, where Unity Pro costs $2,040 per seat (although they may have Enterprise pricing)
Absolutely ridiculous. Many Unity devs are saying they're switching engines on social media.
Copy-Paste from a reply about blocking the telemetry:
Possibly, but can you expect an entire userbase, potentially millions of people, to:
A) know about the problem
B) care enough to do something
And C) know how+be able to apply that block
Especially when there's no effect for end users whether it does or doesn't go through.
A significant portion of players won't bother. Enough that the ones that do don't really matter.
