I have seen more guides for ditching Google on Lemmy in the past few months than I’ve seen in the past decade across all the internet. I guarantee you you can find hundreds of posts here with people detailing how to do it or their own experience doing so. The problem isn’t Lemmy, it’s the communities you are subscribed to.

Edit: I also think you’re underestimating how hard it can be, in particular Google calendar. So many other people use it it’s hard to leave it unless you have some pipeline to convert calendar shares to your new calendar system that also allows it to consistently update. That’s the one that I’ve found the hardest time dropping. Email and gdrive were relatively easy once i sat down and did it.

Google maps is also tricky. I like organic maps but it is not nearly as robust and Apple/Waze are lateral moves
