Exactly my thoughts too. I abandoned Dropbox because there was no upgrade path from free to low-paid-tier. $10 a month is not cheap. Heck, I pay less than that for Amazon prime and that offers a lot more value. I don’t need 2TB of cloud storage - I need something like 100GB.

And as a result, I never even considered it for my organisation when the time came to do enterprise cloud file sharing. That’s how it goes.
