One thing I should mention is that we are surrounded with proprietary software and companies. Almost all of the major tech and publishing companies are proprietary ones. Google, Microsoft, Apple, Facebook, IBM, and Amazon (Big Tech) are constantly working to protect the proprietary software and patents of theirs.
Sadly, the majority of people use almost only proprietary software and these companies are benefiting from them. Now, what we do (supporting the free culture) is against their benefit so they have to advertise against it and target people with false accusations against free software world.
For instance, the Google page about the AGPL details inaccurate (but common) misconceptions about the obligations of the AGPL that don’t follow from the text. Google states that if, for example, Google Maps used PostGIS as its data store, and PostGIS used the AGPL, Google would be required to release the Google Maps code. This is not true.
These companies don’t like free software. This is actually one of the reasons that they use the term Open Source instead of free software.
Now, if they have to pretend to like a free software, they prefer the ones they can control, the ones like MIT that can be used proprietorially. An example is BSD. One of the major developers of BSD is Apple which benefits a lot from the weak BSD licenses.
Copyleft restricts big tech from benefiting and not giving back to community so these companies don’t like it and do everything they can to weaken the copyleft culture so they can survive on benefiting from our community and violating people’s freedom and rights.
