The problem with outsourcing your chat or forum to third parties is that you don't own them. That is correct
The problem with self hosting those things yourself is that 1. nobody will use them because why aren't you just using this 3rd party app that everyone is already using and 2. have fun doing your own spam control
Seems like a bit of a damned if you do damned if you don't situation if you ask me
If I host my games on my own site browsers like Chrome will scream "this is a file that isn't regularly downloaded ARE YOU SURE??"
This should only happen if the file hasn't been downloaded much and is either unsigned, or signed with a new codesigning certificate (the more your file is downloaded, the more reputation it gets; if the file is unsigned, the file itself is collecting reputation; if it's signed, the reputation applies to the certificate instead, so all downloads signed with the same certificate will count).
Unfortunately, the price of codesigning certificates seems to have trippled in the last few years – $188 for a 3-year certificate in '21, €485 two months ago…
