Sorry, Chrome is not open-sourced, Chromium is.

That is a valid point, thank you for bringing it up.

Didn't get it, put your jQuery in another CDN provider has anything to do with censorship?

spend time and resources making sure my site works and keeps working in a marketplace I have no interest in due to the government policies there?

Have you heard Office365?

Yes, I've heard about it. And you would be surprised, how often the answer to putting your company data on other's people computers is: No.

good thing it's the same here for Google data studio...

powerBI cloud has a free tier and does not require a subscription to try afaik: https://powerbi.microsoft.com/en-us/pricing/

in either case, you can work with spreadsheets stored on your computer, but in any case just like Google, you'd have to upload it to work with it.

the pro version doesn't tie you to O365 either even though it uses the same platform

No one mentioned Flume + Kafka? This sounds to be a mature solution.
