Technically speaking, mayonnaise is oil, an lecithin based emulsifier derived from egg yolks, and an acid (which may be vinegar, or mustard, or something else).

If you get a vegan emulsifier to work as good or better than eggs, then go ahead and call it the generic, unprotected "mayo"- because that's what it is, and that's how it will be used.

This blog post/article is a bit hyperbolic with the whole the dirty egg industry thing.

I disagree.

A hamburger is beef. People often call them "burgers" for short.

Vegan substitutes exist, but they are called "veggieburgers", "gardenburgers", or similar, not "burgers".

If you try to sell gardenburgers as "burgers", you're being misleading, and you're likely to run afoul of the law.
