Perhaps exploitation is too negative and it is not true for some cases, but most companies do not employ it or use it as a component because of the restrictive licence.
It depends in usage and license. Not all business models suffer from requirement to provide source code to users.
Even AGPL can be fine for company (e.g. MongoDB in AWS), if it sells service.
And number of companies using Linux kernel licensed under GPL and even making their products based on it is countless.
In that case I agree and kudos to those companies that embrace it and give back. I think it is a way many more companies could embrace if they modified their business strategy a bit.
