I'm especially concerned because Microsoft stopped the support for a native Linux Skype client.

But I think in general Microsoft isn't that bad for cross-platform nowadays. On MacOS I have Office, Skype, Onedrive, etc. And I can access my documents on phones via mobile clients. The tools are all weaker than the Windows versions, but I think they mostly get the job done and are getting better over time.
Can't comment on pure Linux support, but would understand if it's lacking due to the smaller user-base.
The chrome support is still a bit lacking, so Linux users are second class citizens for now. But it's improving steadily.
In any case, as the site mentions, the new Hub is exclusively for Teams, which has its own conferencing system.
Now we're all using Zoom and it's much smoother. /anecdote
Microsoft has a much longer (and quite colourful) history of not-supporting and breaking interop.
However, I would guess that they would still be aggressive against other desktop OSs.
