I'm not a vegan, so the vegan "cheese" isn't named like this to trick me. It's named like this to trick vegans.

Apart from that, there are organizations that act on behalf and to protect consumers' rights. Some of that goes against false advertisement. This is why, for example, products that aren't meant for children or puppies aren't allowed to have children or puppies on the packaging, or the reason why it would be illegal for different products to have packaging that inflates the perceived amount of good that you buy by essentially, selling you air. This is also the reason that in many countries vegan "cheese" is not allowed to be called "cheese" in advertisements on on the packaging. Same goes for vegan "milk" and similar products.

It doesn't have to be about vegan products, it was just a convenient example. In some countries "crab" sticks are only allowed to be called that if they actually contain some crustacean meat. Or products aren't allowed to be called "juice" if they have less than a certain % of actual juice in them and so on.

"Concurrency" in languages like Janet is exactly the same thing. It is false advertisement. You pay with the lost ability to debug and to predict code execution path for nothing, whereas that would've been the price you might have wanted to pay for executing code concurrently. That's swindling. Most likely unintentional in the case of the people working on Janet, but for you, as a user, it makes little difference.
