From the perspective of the employee it basically is a gift (more a benefit).
Employees don't pay for stock in an ESOP; they're earned by being employed there (with different options for how they're divided, but restrictions so they aren't excessively dominated by the highest earners).
None.
The actual "single core", "multi-core" were basically fine last I was aware, but they went so far into apeshit meltdown about the fact that AMD was offering better value than Intel with Ryzen (which is kind of back and forth since, but AMD is the reason I could get a 16 (real, capable of demanding single core loads too) core for $500 a couple years ago, not too long after Intel was selling 6 cores for more than that.) that it undermined everything else.
Anyways, UB's owner didn't like that AMD had good shit so he kept changing the "gaming/desktop/whatever" grade formulas to tilt the comparisons to Intel using more and more hilarious mechanisms. It started with a reasonable "you don't really benefit from games past 4/6/8 cores" and de-emphasizing super high core counts that hadn't really been an issue before, but it quickly degraded into obviously cheating hard by whatever means necessary to punish AMD, with even worse diatribes in the descriptions to match.
