People talk about business as though only the owners of the business benefit. Everybody else pays the price. But aren't the main beneficiaries all the people using these services?
As a German speaker, I experience the quality of German language technical documentation steadily declining. 30 years ago, German documentation was usually top notch. With the first machine translations, quality went notably down. Now, with LLM translation, it's often garbage with phrases of obvious nonsense in it.
This is especially true with large companies like IBM, Microsoft or Oracle.
I guess the situation is better for languages where translations only became available with LLM.
This is explicitly not a benefit to the people using the services.
But more to your point: you might not have run into languages that didn't have proper translations available, but billions of other people did. In the past I read a machine translated book before. It was almost like a derivative work because it would randomly differ by a huge amount from the source material.
