Jeph has made numerous factual errors of this kind in the past. It is quite clear by this point that he does not perform even fairly basic googling regarding factual background points that would arise in the comic. For example, in the very last plot he kept having Nelson refer to an 'NLRB violation,' which isn't actually a thing. The NLRB (National Labor Relations Board) is an agency of the government, the NLRA (National Labor Relations Act) is the actual law governing the rights of employees.
The other part of this is that it doesn't actually benefit the story for Marigold and Aurelia to become unexpectedly wealthy via streaming. Marigold becoming a streamer and making roughly the same amount of money she made before with massively greater job satisfaction (a much more plausible level of popularity) would be a far better outcome for the comic. Likewise, Aurelia becoming independently wealthy actively imperils an existing storyline: Claire's job search.
