Right, like I said, there's a difference between the level of support you're receiving and what the internal infra receives. Your experience is totally unrelated to the developer tooling teams at FAANG. Those teams don't, generally speaking have external clients, and when they do they don't have the same support requirements.

It's like if I said "I really enjoy the concierge service I get as a premium partner of my credit card company" and you replied that you didn't get that perk. Sure you don't, but I do as do the other people who pay for it.

Your experience as a not faang engineer doesn't provide any insight into how things work internally, and it's really weird to say that they are wrong. Or on other words, yes, FAANG companies can provide different levels of support for things. In the case of they're internal dev tools, the support is better (and a lot of the tools are generally better, although GitHub is finally catching up)
