The CEO receiving a salary that was agreed upon through negotiation is very different from shoplifting and I hope that you can see that and come up with a better analogy.
It's different, I don't think they're claiming that it's directly equivalent, but they were responding to the claim that "7 million isn't significant in the grand scheme of things", and they're arguing that "just because it might not be a significant number doesn't necessarily mean we just let it slide".
I don't think anyone is accusing the Mozilla CEO of "stealing" the money.
Now there's another sector of society ripe for a shake-up by DoBE - Dept. of Business Efficiency - which has as a stated mission to rid the business world of the parasites is has picked up in the last century. From overpaid CEOs to overpaid corporate lawyers, scrape 'm off just like you'd scrape the barnacles off your vessel's hull after having been at sea for an extended period. While a business needs leadership and legal support it does not need to lend itself to supporting the bloated class of parasites which has grown to be the norm for some of those functions.
The way to go at this without breaking incentives for people to start new businesses won't be easy and it won't be by way of redistribution like socialists (etc.) are so fond of. The best way is most likely to change societal norms so that it will no longer be seen as acceptable for a company to have a CEO (or CFO or COO or CxO) hauling in more than, say, 24 times the average pay in his or her company. That '24' number just fell out of my sleeve and probably needs some more thought but the gist is clear. In 2023 the average pay ratio for CEO to average was somewhere around 270 to 1 and that ratio has been going up for decades. By now you'd think that CEOs would have priced themselves out of the market but that does not happen. I suspect this has a lot to do with the makeup of the boards of directors which decide over CEO pay being manned by other (aspiring) CEOs who as a group have an interest in keeping up CxO pay.
Yes, this is a difficult problem to really solve but also yes, I think it is a problem and I think it is worth solving it.
I think you will find that CEOs either have a significant share of the company, or are the lackeys of someone who does. In other words the only "negotiation" they did was negotiating with themselves.
