To be clear, I am upgrading from Python 2.7, but while I do it I'm not building in a way that requires any code from Google and will make sure the app is platform agnostic.
It doesn't really matter how many years of notice they gave me, I just haven't had time to do it.
Having any sort of code on python 2.7, means you don't give a rat's ass about security. It also immediately means your code should be assumed to have back doors, vulnerabilities, because python 2.7 almost certainly does!
This is what happens, when no one is maintaining software.
Security is more important that anything, certainly than having time or not to update your code.
You're 100% in the wrong here, and Google is 100% in the right, and I hate Google more than spammers, more than pretty much any other company there is.
They're not wrong here, and it hurts me to support their stance.
Fix your stuff. Stop blaming others. I doesn't matter why you're in the situation you're in, you're wrong to be there. No matter what.
again: not everything sits on the public internet, and by the time someone gets access to the application there are far more serious concerns then python 2 vs 3
this also really highlights the problem with python's 2 vs 3 split: there is a large body of work that will never be updated and will forever run 2 including actual web/publicly facing code. And saying "just upgrade because security" isn't going get much of that code upgraded.
It doesn't really matter how many years of notice they gave me, I just haven't had time to do it.
