The fact is that we don't pay for component...
The mentioned components are released under LGPL...
We use only free software... with their licenses...
Yes, you use free software as in "free speech"... but you violate the LGPL license when you change the component name and furthermore removes the original license statement and replaces it with your own copyright notice.
A license for a software product whether provided in source code or binary form still apply. In this case the component are provided in source-only form and needs to be compiled to binary representation.
An example:
If I forked the Lazarus project, removed every reference to the GPL/LGPL license and indirectly claimed the source code is produced by myself with a copyright notice in every source file, then I would violate the GPL/LGPL license and furthermore been real screwed as I could be prosecuted due to license infringement.

That's why it's so darn important to have proper licenses in place and proper management of 3rd party licenses - even while using GPL software. Many of the big electronics manufactures have had real issues with using GPL licensed products in their televisions, routers, dvd recorders and so forth, as they "forgot" to make the source code of the included GPL software available.
