What's the source for the amount of employees? I couldn't find anything about that, let alone specifically 50 or 75.

I also think it's unreasonable to say that in a 50 person company that sells junk and makes YouTube videos that the median salary would be 100k. And even if it was, 50 * 150k is $7.5 million, not "around 10 million". The difference is significant considering we're talking about a $2m fine.
