> The CJEU ruled that it's legal to bundle PCs with software without indicating their prices separately, and that offering consumers no choice but to buy the PC with the software is also legal, "unless such a practice is contrary to the requirements of professional diligence and materially distorts or is likely to materially distort the economic behavior of the average consumer with regard to the product, a matter which is for the national court to determine by taking account of the specific circumstances of the case in the main proceedings."

IBM just included a copy of FreeDOS for every PC before it sold it's business to Lenovo.

This was over a decade ago.
