Imho a decision that doesn’t make sense, Google already has paid for all the infrastructure so running the service to them is pure profit, not to mention the lost possibility to upsell Google workspace (paid gmail with a custom domain) or Google cloud services to all their customers.
Although I would never subscribe to something from Google for my business, then when they eventually change mind and kill my product, i have to migrate in an hurry. I’ve been hurted too many times
I don’t really have that issue but I realize most people do. I prefer to use the web client for desktop and the app for iOS. Privacy and encryption is a huge pain in the ass and it comes with a lot of inconvenience, but the flip side is knowing that I paid for a service that is going to do it’s best to keep my data secure and most importantly, not look at it. When I heard microsoft was reading peoples emails and unlocking files in onecloud I was floored. I can’t believe we trust these companies with any type of messaging service.
