AFAIK you have to have two parties to do a deal! A buyer and a seller! So blaming the buyer is never 100% of the story. Someone on the selling side had an interest, too.
My workgiver acts the same way on the business floor - buy small companies, take over their R&D and portfolio, keep what's interesting, throw out what is not of any profit. Sometimes the brand-name is worth more than the company itself, and sometimes only the two R&D guys or the salesman is of any interest.
I hate that it is that way novadays - that companies cannot co-exist anymore because they need to make more profit than the year earlier, which in return means another company makes less profit and maybe, dies. Nothing against companies colaborating and doing great things both of them wouldn't be able to on their own (see Behringer's digital mixing line thanks to Midas know-how and Behringers infrasctructure).
All this results in a very fast and short-thinking business, where companies are owned by huge investment banks who try to sell within 3-5 years with max profit. So the whole business strategy is designed for 3-5 years, and what's coming afterwards is a surprise. We been there, nearly got extinct.
If a company wants to keep that principle going, in the end there's one man in the factory building all the guitars in the world. That's the ultimate end of the "we have to make more profit next year" principle
