So complaining about Github proprietary tools and at the same time supporting Apple and Google for doing the same is a bit contradictory. Should be using an open OS and browser.
From a software eng infra standpoint, in general, ok. But we can look elsewhere.
In the mobile space, for example, it's hard to deny iOS & Android, Appstore & Google Play.
In terms of privacy, the internet is a complete failure with Chrome, Google Analytics, etc.
A large chunk of the most relevant software businesses go to the extent of mandating developers to use Apple products. I experienced this myself, when I wasn't allowed to use a PC running Linux for "security reasons". Like if Apple OS is safer than Arch. That's a big point of failure, in my opinion...
