Kind of a silly question, as there appear to be other sources of commercially-produced food, besides Pepsico products. And I suspect growing my own food would be a sight easier and safer than making gunpowder in the basement.
No sarcasm, but that's a pretty deep rabbit hole. It wasn't Pepsico, it was Senomyx with the HEK cells. In addition to Pepsico and Nestlé, Senomyx partners with Fermenich which appears to partner with the whole dang International Organization of the Flavor Industry. Depending on exactly how prolific the machines using the cells are in taste chemistry it's credible that no food with any artificial flavor at all hasn't been run through a company using the HEK cells. And I only trolled Google for about 10 min to find those connections. There may be more.
Now I'm neither telling you to ignore them or accusing you of hypocrisy, so please don't take offense. I know you and many on this board feel strongly about the issue of abortion and the use of embryonic cells, and I have zero interest in starting THAT discussion. But the above question isn't as silly as it may seem at first glance. Embryonic cells are pretty versatile, have been available for research uses for some time, and are not necessarily so e thing you advertise the use of in your company. Boycott of all companies that use them even at one remove (as Pepsi's use) might well set up a boycott of a whole bunch of stuff.
