> Do they enforce this limit just to reduce support queries from low-profit customers?

Almost certainly. To quote patio11: "Pathological customers: they get things for free and then ask for their money back." The more money a business has, the more professional it can afford to be (literally) in dealing with you. If you want 80% of the money with 20% of the effort, draw a line between the head of your profit distribution, and the long tail of pathological customers who think they're owed support because they pay $coffee per month, and then keep raising your rates until everyone in that long tail leaves.

Though there's also the fact that for ≤ 5 people, using your personal Dropboxes and having a Shared Folder for your business works just fine.

I totally understand the reasoning.

Re: personal + shared folder, that starts to get a little messy when you're sharing folders/joining shared folders with outside people. Doable, but messy. Another option is one account for the business, with e.g. 2 people logged into it. I do this, plus a hacky workaround to also have a personal account logged in on my laptop.
