It seems to indicate that if Amazon was employee-owned today, the first thing they would vote to do is convert future hires into non-owners, because that's what the founders did when it was actually employee-owned.
Not entirely sure what you're saying here. Amazon still provides stock to employees as part of the comp package, AFAIK.
It is a good practice for companies to include stock as part of the pay package. It encourages alignment of the company with the employees. Very, very successful companies follow this model, such as Microsoft, Apple, Amazon, Google, etc.
