UPDATE: Scienceblogs has quickly caved and removed Food Frontiers from their lineup.
The science blogosphere is up in arms about Scienceblog's (a division of Seed magazine) decision to introduce a blog written by PepsiCo ("Food Frontiers") and its scientists. Some Scienceblogggers are resigning (David Dobbs and Rebecca Skloot -- Carl Zimmer is keeping a rundown here), and I've seen calls for the National Association of Science Writers to write Scienceblogs a letter expressing their displeasure.
Let's note: The PepsiCo blog hasn't even written anything yet, besides a simple introduction.
This suppression of speech not yet even expressed is disappointing, merely because a mob shouted it down. Imagine if this had happened in, say, climate science, where perhaps a Limbaugh- or ClimateDepot-inspired mob floods federal agencies and science organizations until a certain grant is revoked or a speaking invitation taken back.
It would have been far better to keep the blog up and let commenters chew it to pieces (as they would), if the science really was bad.
Intolerance and prior suppression of speech is unacceptable no matter where it happens.
