Maybe, maybe not.
Imagine a scenario where a big search engine who wants to put their current virtual monopoly into concrete. They already closed a deal with their biggest competitor, leaving the disappointing third market participant with very little chances to ever pull over.
Their real threat comes from startup companies. Small, young, fresh, hungry, bright teams that create a PR blitz and quickly take over the market. This is very very dangerous for the market leader.
Now imagine further that someone somewhere at the market leader figures out a plan to prevent this from hapening. You take a bunch of (ex-) employees, hand over some cash, create said PR blitz, and deliver - crap. Upon launch day, the site shows mistakes anyone with a basic understanding of this market would have avoided (e.g. missing about page). It's an immediate and massive failure.
<devilish smile> Now, how likely is it, that the media will write about the next startup to threaten that market leader?
