Claiming you don't clone the repository to your local PC is just false and will probably take more time than it does on GH.
> Excuse me, WTF?
This is what I ask every time I see someone saying e-mail is an okay way to do contributions, continuous integration and issue tracking.
> How is it negative exactly?
It's a ton of bad UX and UI. It negatively affects basically every component of development for everyone not accustomed to the bad tooling.
> All that Github and Gitlab bug tracker has is pretty UI, which doesn't mean good UX.
Better just good UI than bad both.
> Secondly, that puts all of the FOSS projects in one basket
You are out-of-touch to the possibilities available right now, Gitlab can be self-hosted.
> If <nation> wanted to deny access of FOSS projects for <another-nation>, it would just have to exercise power on Gitlab
Gitlab has no control over the independent instances of Gitlab.
> Sending bug reports to Mozzila, PostgreSQL, etc. was a good experience for me.
Sending bug reports to those companies using GH/GL has been a way better experience for me.
> Firstly it doesn't leave space for using email, which a lot of big projects have accustomed to using
So what? There's a lot of old and bad "protocols" we've killed.
> Linux was started in 1990s. Is it majorly out-of-date?
I was not talking about Linux _per se_. The way contributions and development is done is majorly out-of-date and is stifling, yes.
