I think it's partly because the JS ecosystem doesn't historically have a solid standard library. Doing simple things can require checking for null/undefined/does the runtime support it, etc. Why do it the hard way when you can NPM install it and call it a day?
I'm excited because while B2 + Cloudflare is great, the speed+latency isn't the greatest for some applications. So there's definitely a place for R2 here to compete more with AWS S3 than B2.
I used to have a Google Home Mini in every room. I've switched to Alexa because I trust them to keep it going a lot more. It helps that Amazon makes money off Alexa since I buy things through the device sometimes.
Outside of GSuite/Workspace I really don't trust Google products anymore and I'm tired of trying.
