I don't think a model trained on a single company's data would be nearly as helpful as a model trained on all publicly licensed code on the internet. But suppose it were...

What if I'm not a massive corporation with millions of lines of code to train on and I want to pay for an AI coding assistant? Doesn't this make it effectively illegal for me to purchase such a product for a reasonable price when big companies will presumably be able to use it without paying the tax?

Another situation - let's say you're a company that contributes heavily to open source, but also accepts external contributions. Could Facebook train a model on the React codebase, for example, without having to pay the AI tax?

Another situation - suppose I start an LLM coding assistant and sell it to my friend. Presumably I don't have to pay the tax as a "low revenue" company. Then I get acquired or get some huge seed round and suddenly my customers have to pay the AI tax. Doesn't this just nuke all my customers?

Anyway, as a software engineer, I personally want people to use my code for whatever they want to use it for, without having to pay me for it. I indicate that by using an MIT license. Why throw that precedent out the window?
