I can't blame them, but I don't have to like it.
Dropbox has gone Photobucket on us. When I started using Dropbox, at least a decade or so ago, there was no limit on how many devices a free account could connect to the account. As a widower whose only child is an adult not living with me, I'm only one person but circumstances have conspired to leave me with three desktop computers, two notebook computers, two Windows tablets, and an Android tablet. In 2019 Dropbox changed their rules, so that new free accounts could only have three devices connected. I ran afoul of that when I gave away an old notebook and wanted to add a newer one to my account. Couldn't do it -- so I was down to six devices (I never put the Android tablet on Dropbox). Supposedly, existing accounts were grandfathered as long as you kept the same devices, but you couldn't add new ones.
That has apparently changed. Last night I fired up the #2 desktop and tried to access a file on Dropbox. It wouldn't allow me access. I got an error message telling me that my account has too many devices on it, and that I have to select which ones I want to remove.
Well, I'm sorry, Dropbox, but a cloud service that only includes half of my devices is useless. And no, I'm not going to upgrade to one of your paid plans. You sucked me in by offering a free service. I understand that you want to make money, but that's not my problem. I could tolerate the grandfathered limit, but now dropping my account to three devices is unacceptable.
So I'm moving my files from Dropbox to pCloud. I also have a GoogleDrive account, a Microsoft OneDrive account, and I just signed up for a (free) account with Box -- and they all allow me to use all of my devices. I think I'll get by just fine without Dropbox.
Sorry to be petty, but I hope Dropbox becomes as irrelevant as Photobucket has become.
