Except there's also a bunch of companies with special dual class share structures, where the founder gets way more voting power than everyone else and you can't even buy your way in. A lot of tech companies do this. This is, functionally speaking, an autocracy.
If you want an actual corporate democracy you would need to assign voting rights to everyone working at the company, aka build a co-op. Co-ops are a great corporate structure in a lot of cases but you can't really raise capital that way because VCs all want on your cap table, so all the big companies wind up being plutocracies.
I employed a painter a few months ago, and I decided what colour the kitchen now is.
This is just wrong. As kmeisthax mentioned, shares can have different voting weights - if any at all. Many shareholders have no voting power.

Did you actually employ them, or did you buy a specific service?
The same phenomenon is happening with "Opt-In by Default". This is newspeak.
Keep in mind that the US is a democratic republic (thus a democracy) yet spent the first part of its history restricting who could vote based on (approximately) both gender and race.
Voting is a democratic instrument, but a blunt one and not the most important.
"...those who spend five minutes voting every three years and call it democracy..."
Majoritarianism is undemocratic in that any desire less than 50% + 1 is deprecated.
If you care IMO the most important feature of a democracy is rule of law and access to the courts.
