The author responded to you, but I think this deserves emphasis. True privacy is not about additional features or promises made by a cloud provider. It's not private unless you handle the data yourself, period point blank. This should be obvious.
> It is the managed infrastructure. Outage? You can keep sleeping.
I don't think an outage in a third party service I've depended on has ever allowed me to keep sleeping. In reality, I've been awake, dealing with outage fallout, keeping up to date on status updates, and overall just feeling in the dark, unable to improve the situation for my customers.
That's not saying that depending on a third party service isn't sometimes the right move, but "I get to sleep when there's a problem" isn't a consideration there. The pager still goes off.
BTW, event replaying is coming in 2 weeks with Rudder :) Also, we are developing extensive test suites to check for API depreciations etc. That was one of the reasons we picked JS for our transformations - shipping an update would be easy. Infra outage - sure but you probably have a prod infra to manage anyway so why not one more piece.
No doubt segment is a great product and there will always be folks who want its simplicity. However, at some scale companies should take privacy of their user data seriously.
