This is a consequence of unintended good intentions.
Back in 1992 Bill Clinton ran on the idea of CEOs make too much money, the government should limit that. Simple idea, and simple solution: if companies pay CEOs more than $1m, they should be taxed much more on the amounts above that. Corporations are tricky though, in the final law that passed they had their lobbyists successfully insert a paragraph that basically said "oh, but any compensation paid to employees via stock options won't count as part of that $1m cap". Famously a few people foresaw what a problem that could be and tried to kill it, including Robert Reich the treasury secretary, but the lobbyists had too many congress people in their pocket and it passed.
After that stock compensation has become a huge part of companies, not just CEOs but upper management, the board, and even regular employees at tech startups - famously thousands of Silicon Valley millionaires are minted every time a big company goes public (or bought). Companies LOVE it, they simultaneously can give out big bonuses in the form of options, AND IT IS A NEGATIVE TAX CONSEQUENCE. If they give out $100m in theoretical options, they can say "Oh, we lost $100m because of these options and that offsets $100m in profits". Its not quite that simple the math gets bogged down a lot, and there are still taxes they pay and of course when the employee/CEO/etc sells the options they still pay taxes.
Anyways the point is something that seemed like a good idea was hijaacked to be a huge problem, just like Bill Clintons "lets crack down on crime" probably led to the biggest crime against minorities in impoverished neighborhoods by sending largely people of color to jail for stupid drug crimes, depriving families of fathers for generations, and creating a massive police and prison industrial complex the country is still under the heel of.
Before we do any "solutions" to this kind of problem it needs a lot of thought and smart people thinking about all the loopholes and making sure there are ways to stop them from being abused in the future. A political win for 1 month can be a Pyrrhic victory a decade later.
Anyways this problem tends to get exaggerated in raw numbers, Blizzard doesn't pay $0 in taxes. They still pay income taxes, social security, taxes on stuff they sell, local taxes, land taxes, taxes on goods purchased, etc. They can just offset almost all their profit by giving employees stock options. They don't "get" money from the government like some welfare payment if that puts them in the red, they can just carry a portion of that as offset against profits in the future. There is some misinformation being propagated. When those employees sell their stock they pay capital gains taxes, although it also can be mitigated heavily and rich people use similar "offset" tricks to reduce their tax share. Ironically its the poor and middle class who never get any real tax breaks.
