That’s not the extent of software freedom. You can personally modify someone else’s free software if you want. But if you are providing the modified software to others, either as a free or a paid product, then you have to provide the users with a copy of the modified source code. Modifying GPL licensed code and using it commercially without supplying the modified source code is the primary source of free software license violations.
