Okay, look. There's two universes here. Universe A is where split up the features of our product into tiers based on "value" -- some arbitrary groups based on how useful we think each feature is, how expensive they are, how long they took to develop, estimated person-hours saved, whatever. Sweet, it feels right. Now the free/low cost tiers are genuinely less useful than the higher tiers. Pay more for more. SSO probably still lives at the mid or enterprise tier for no other reason that it's a PITA, is the cause of like 20% of support requests, and our SSO vendor charges us per month per SSO connection.
Universe B is where the free/low cost tiers have every feature except for specifically the features and increased usage limits that get SMBs and Enterprise to pay us.
Both on the sales side and the user side I want to live in Universe B.
There is no magic universe where "just increase your value proposition to Enterprise customers" -- it's the same product just carved up differently and non-enterprise customers lose in Universe A.
