As consumers we can use or not use platforms like Google, Twitter, etc. as we like, or not.
Colab’s ban will be good for small 3rd party GPU cloud providers and that is a good thing. Same thing with Twitter: in the last month there is now better material on Mastodon.
Can you use Colab from VSCode? Notebooks are great for exploration but not for complex projects.
You have to be careful to back up your code frequently (what I did was push to Github) since your ssh session goes away when your "kernel" (or whatever your colab session is called) goes away. You wouldn't have this worry if you were just using the web interface, since the code is always saved.
I'd imagine that, if you want to use VSCode, it's remote editing features, which I keep on hearing a lot about, would come in handy to edit over ssh!
