I do not agree with this approach, not with bon jovi at least. I think some points if they could have known, because they use the same co-writer in a period of time in which may be recycled ideas from other compositions for other artists... but do not think it's that deliberate.

However, I believe that many of the songs that resemble other, is because Jon copy greater or lesser degree to make your own song. Sometimes the result is good, but others are too obvious and is ridiculous.

Some songs of Foo Fighters also have these rip off, even Led Zeppelin or The Beatles also went through that. But I do not think it's a matter of record companies, I would say that is rather things the artist is willing to go - to borrow (stolen) as his inspiration, when his muse not appear.
