> I think it makes perfect sense for somebody to say that any loan that is backed by stocks granted on the basis of RSU, incur some additional special taxes

Based on the numbers published though, it does not appear like these people are taking out loans with shares as collateral.

E.g. Bezos declared 4.22B in income and paid 973M in tax. This leaves him with more than 3 billions after tax, so I sincerely doubt he also took out a loan.
