I’ve had like three primary email accounts since the dawn of the popular internet in the 90’s
The first was Hotmail because that was a big deal at the time.
The second was google because the interface was slick and it came with (what was at the time) a lot of free storage.
The third is protonmail specifically because after decade+ on Google I realized they pretty much have the keys to the kingdom on my life’s data. All my personal relationships and business being filtered through their inbox for a long-ass time. Just because they “know me” inside out for a significant part of my life doesn’t mean I gotta just keep feeding them data indefinitely.
