No, using the LGPL code done by third party is still free of charge.

And we also have seen many times developers who released their code as MIT never seeing a dime from these big companies (such as Corejs developer).
LGPL is the way to go to ensure that big corps who make money out of an open source project do pay up. You don't want to release your source code? Then pay for a commercial license, end of story.
Right, of course; hence the failure of Linux and the dominance of the BSD family. /s
But yes, using permissively-licensed components absolutely
is* a good thing, including for the users, who get higher-quality software with less dev time and lower cost of development. Obviously I'd prefer that it was all GPLv3, but given that the alternative in practice is probably fully-proprietary software from scratch, I think BSD is better than nothing.
