Yep, and Microsoft does exactly the same thing. I have an open source video review tool for esports teams that I give away. On both Windows and Apple I'm expected to pay a yearly tax (~$200 on Windows from memory) to distribute my software on that platform. The owners of these platforms make no allowance for open source authors to distribute without that fee.
This is done in the name of "security", as if malware authors couldn't afford to pay it.
