This is what had been surprising to me in my experiences... first few startups the cap table was shared info but no specifics (investor pool 33%, employee pool 7%, etc) so at least you knew the rough outlay.

Then one recent startup was championing transparent salaries but wouldnt share anything about the cap table which seemed odd to me.

My current company the CEO answers questions about the stock outlay but not specifics but also doesnt claim to be transparent.

I just assumed from my earliest experiences most small companies were happy to explain the cap table and walk folks through dilution events.
