Is Github contradictory of open source values?

When developing Open source , one of the core values used to be the independence from the tools used, especially when those tools are proprietary. An example can be the use of gcc instead of an Intel compiler.

However, the convenience of easy-to-use tools such as Github outweights the political reasons behind open source[ @eghbal2020 Working in public: the making and maintenance of open source software ]. That is why so many projects, including some very big, such as Python, moved to Github.

The question that remains is, therefore, what are the open source values ? Do they change over time?

Another interesting point is that Github does not take community suggestions. Developers had to create a repository within Github to complain and to suggest improvements. Is the governance of Github aligned with the interests of their users?
