LyX is licensed under the GPL and can be used in accord with those terms. So yes, you can use it as you wish, without charge, though if you or your company finds it useful, we'd absolutely appreciate a donation. Donations of code would be even better. If you want to modify the LyX code and/or distribute it, then there are rules that have to be followed, but that's a different matter from just using LyX.Is Lyx without costs, even if companies use it?
