You're normalizing it and making your students use it though, so it's really not "it affects me, but I don't care enough", it affects others as well. And let's not kid ourselves: once it's established, nobody will switch to something else, because they'd have to explain and guide everyone they want to talk to to install another app etc.
I live in France. Overnight schools were closed and the existing school platforms are a joke.
Beside the fact that they crashed, there is no interactivity built in.
So as a parent of two children I would have been delighted if the teachers switched immediately to Zoom or Discord and I truly do not give a fuck (not that I do not care, I do not give a fuck) about privacy and whatnot when it comes to middle age history or derivatives.
This is this, or me having two jobs.
So except if the software keeps on spying after it is switched off (which would be unacceptable) they can use Zoom or whatever if the teaching process is maintained.
If the teacher asked me to install The Catholic Video Conferencing System my only question would be where to get the msi from. (again provided that there is no spying afterwards)
This is really kind of funny, because this exact thing happened literally less than a year ago. It was technically a vulnerability, but they refused to see it as such and fix it until it was disclosed publicly and they had a wave of negative PR. They literally allowed anyone to connect to the webcam on your computer through an always-on server which remained installed after you removed Zoom from your computer. https://medium.com/bugbountywriteup/zoom-zero-day-4-million-...
I can't believe everyone has forgotten this quickly. Zoom is not a trustworthy company.
What they did is a shame. I do not know yet whether to attribute it to malice, sloppiness, immaturity, or a combination of the above.
Your second point I disagree with; I think if people raise objections, encourage people to switch, and volunteer to shepherd others through the technical details -- then people will be agreeable, and we'll see a shift which will gradually become pervasive.
It can change rapidly in small communities, e.g. you getting everyone in your department together, deciding on $goodAlternative and using that whenever possible (in addition to Zoom, because you'll still have to communicate with the outside world). But at large?
This doesn't square with any experience I've ever had trying to get $alternative_technology adopted because of $principle in favor of $default_thing, and from what I've gleaned talking to others, and reading the experiences of others online, the problem isn't me.
Maybe post Cambridge Analytica the world has changed -- I at least don't get looked at like I have three heads when I tell people I'm not on Facebook anymore -- but if folks are still responding to complaints about privacy issues like this with what amounts to "meh, don't have the energy" then I'm skeptical. If zoom becomes "the standard," I don't think the inertia will be much easier to overcome.
As soon as something goes wrong with your solution - everyone goes, why aren't we using zoom. Literally totally non-techies - that will be their first bit of feedback (I tried to go with google hangouts).
