Prusa is getting tired of investing R&D and then having someone else copy that. Someone else without an R&D budget can make things cheaper because they don't have that budget.

They are most tired of investing in R&D in the open and then having some company do a patent in their country. The company then sues them for infringement.

That's sad. But how does that affect me as a potential customer?
