I’m annoying that they used to have a single membership that includes everything, which I bought, and now they keep adding features and telling me I need to pay for those. But there’s no clarity over what is/isn't included with my membership or the offered upgrade, so it’s pretty certain they’ll be asking for more money again in the future.
Considering they make money selling information/data/research, and aren’t transparent about these upgrades, I’m not giving them more $$. I understand additional functionality costs them money to roll out, but that’s their business, not mine.
