From Wikipedia:

"The Flavr Savr turned out to disappoint researchers ... as the antisensed PG gene had a positive effect on shelf life, but not on the fruit's firmness, so the tomatoes still had to be harvested like any other unmodified vine-ripe tomatoes. An improved flavor, later achieved through traditional breeding of Flavr Savr and better tasting varieties, would also contribute to selling Flavr Savr at a premium price at the supermarket.

...

The failure of the Flavr Savr has been attributed to Calgene's inexperience in the business of growing and shipping tomatoes."

Sounds like Flavr Savrs were just a failure. I don't see anything about alarmists.
