Thanks, I was wondering what "SSO tax" means. I see it differently. The enterprise plan is that the company really wants to sell. But it gives a discount to small companies that don't need the enterprise features like SSO, at least not from the beginning. I think it is very similar to freemium pricing - extra features, extra cost. Of course, when I look at a product, I look at all the plans and decide if it is worth the money now and in the future. I may feel pity and not buy it. But I never blame companies just for their pricing page.
