We loved Dropbox and had a family subscription. One of the main reasons we stopped using them (besides it being a US company and Trump threatening declare war to a fellow European NATO ally) was that even though we were paying users, they continuously badgered us with upsells. Using Maestral as a client made things better (at the loss of block-level sync + now unmaintained), but every time I had to log into the web interface I got stupid upsell ads.

I once contacted their customer support about this and their answer was "Oh really? Can you send some examples?" So I sent them screenshots of all the upselling banners, popups, etc. that they showed and I never heard back from them.

It also didn't make sense at all. Why, if I'm using Dropbox for family use, would I upgrade to a business plan?
