Maybe there's more to the burrito shop story than is presented here, but all that I get from this description is that many people felt (reasonably or unreasonably) that the owners were improperly profiting from culinary knowledge they had gleaned from contact with indigenous people, so they refused to patronize the shop, and consequently the shop went out of business. If that's what happened, then you'd best leave that one out of the parade of cancellation horribles because that's not really cancellation, it's simply experiencing the business consequences of too many people not wanting to patronize your business, so including it in your list undercuts your argument that cancellation from the left is real.
