Thank you

From what I understand, yes. Bitcoin is open source so any developer can create a pull request, but only those with commit access can interact directly with the main repo. Consensus is also a huge factor of the Bitcoin Network

This group of people can update core base but all big changes are coming with community votes

Wladimir, as the lead maintainer, is the only one that can revoke Commit privileges from one of the Bitcoin Core Maintainers?

[witcher_sense]

Maintainers sign every merge commit with personal PGP keys to make sure there weren't any abuses and malicious code injections from GitHub employees, for example. However, if GitHub turns fraudulent, Bitcoin will immediately migrate to another development platform. Bitcoin Core maintainer makes merges only after team of developers and cobtributors agree upon any changes. Maintainers set pre push hook to ensure they don't push unsigned commits. Maintainer must consistently contribute into Bitcoin Core codebase or he will be deprived of that role. Being Bitcoin Core maintainer is not a privilege, it is rather a hard everyday work.
