I think that's just a cliche and reality proves the opposite. A lot of acquisitions are going on constantly in all industries, and there is no or very little correlation between that and sales.
Do you have anything to prove that? I don't have anything to prove my assertion (other than personal opinion) so I'd be interested if you had something.
Can't remember when was the last time that change of ownership influenced my decisions on buying or using products, at least immediately after acquisition. Of course new owners can dump the product, but likewise they can improve it. I didn't think about it before starting this discussion, but it seems to be true.
