Font vendors seem to _love_ coming up with weird snowflake licensing schemes rather than trying to stick with something well understood.
There are no page view limits for websites (no trackers), installation limits , epub/ebook limits, etc. Basically it is along the lines of FontSpring's worry free license and I think its even better.
You might look at the jetbrains individual license for some language that I think is more clear and objective: A personal license must be paid for by a single named individual, not paid or reimbursed by a company, and is not re-assignable, while the organizational license is more a "floating seat" that can be paid by a company and assigned to individual employees as needed. That helps sidestep the mess of trying to define what is "professional but not commercial."
Also, under a subscription model I'd want some assurance that previously created print materials receive a perpetual license even if I didn't renew and that I wouldn't have to try to excise it from everywhere I've used it in the past if the license ever lapsed.
