This is the perfect example of why privacy matters. No matter how much you trust a parent company one day when the investors come knocking they are legally obligated to liquidate all assets to the highest bidder. Today its 23andme tomorrow it could be discord, google, amazon, Facebook or any other tech company.
I researched this a bit previously for proton and I think there was one case where someone had their account deleted but they were using the service excessively. I also read that if you do upgrade to a premium subscription support can help you merge your accounts together so I guess they kind of support it. If your making a few accounts even on the same IP you are probably fine just don’t login to them in quick succession and you will probably be fine. I do suggest you use an aliasing service when you can.
