There is no specific evidence for this, but it is a possibility. Balancing remote possibilities and accepting some that are beyond our control is what separates the sane from the tinfoil hat crowd. Personally, I would try to stick to apps by companies headquartered in your home country. This is difficult outside of the USA and probably impossible outside of the next 5 top software hub countries.
Why is that? It seems like the opposite would be the best advice: make sure to use something from a company not headquartered in your country. Most people probably have more to worry about from their own government than anyone else.
I like it! I'd totally give that TV series a try!
If yes: do not use Zoom right now. If no: do what you want.
But I wouldn't use it for work meetings.
The Chinese government is the last entity I'd be worried about with this kind of information (unless, of course, you live in China). Certain criminals in your own country are a much bigger concern.
This is similar to the concern some of us had over giving local government departments access to our full Opal card public transport travel histories here in Australia. Not all government employees are up to no good, but some are. Don't give them more than they need.
"Someone", sure, but not the Chinese Government! That's a completely different threat model!
See their push into universities.
Because China=bad, Google or Facebook or Microsoft (which all provide data to) or NSA =good
