That post is only in regards to the CI feature. But today, even basic registration requires personal identification. You cannot even report bugs on open source projects without

Even Github does not require any personal information, so there are certainly other ways.

Since that still requires personal information, this is still a very questionable process. (not to mention it took me a day to not be asked for a cred card)
