The article is talking about officeware, so documents, file sharing, chat and e-mail. My comment was about documents specifically. I’m sorry if your work is frustrating, but as a non-academic, what am I supposed to do, except vote for candidates that promote education? That’s been my priority from when I was old enough to cast a ballot.
Your university’s leadership failed you in the decades before today when they went for closed-source, foreign-controlled options. I cannot describe the stupidity of hosting research data on American services, a choice that to me points either to stupidity or bad faith.

But the crux is still this: the best time to switch was the previous 30 years, the second best is now. Saying “we can’t do it!!” only lets the tumor grow and grow. Nobody’s expecting change overnight, what should be expected, though, is action.
