I'd ignore that comment.
In life I have generally found, myself included, that the more financially and professionally successful you become, the more your reputation amongst your peers and clients becomes far more important than a few pounds/dollars here or there.
It's just a typical internet throwaway insult that is all too easy to hurl at those who have become successful. Unless the poster has personal knowledge of the individuals concerned and their personal motives ?
Of course running a company where you are personally responsible for the livelihoods of all your employees - you know - making sure their salaries are in the bank so they can put food on the table, feed and clothe their families etc, tends to focus the mind somewhat.
I wonder if the poster has ever been awake all night staring at the ceiling, worrying if he will manage to make the payroll at the end of the month. I've done that, and I've nothing but respect for anyone that sticks their head above the parapet and tries to build something.
Frankly if someone said that to my face, I'd find it deeply insulting. There again, I doubt that anyone would ever say that to my face, much safer to hurl personal abuse from behind a keyboard.
That's not to say there are not those who run their business in an entirely cynical manner. They exist - but they generally get found out pretty quickly.
