You can come down off of your high horse, guy. My family has been eating home grown tomatoes before anyone referred to them as “heirlooms”. There was no such thing as hybrids 50 years ago. In my garden in PA Early Girls grow best. Jet Stars are second best. Heirloom varieties have low yield and are prone to blight. I enjoyed my last vine ripened tomatoes in early November when “heirlooms” would have been a fond memory.
Another reason to grow heirlooms is because they breed true. Hybrids do not. You can save your heirloom seeds every year and never have to buy any more seeds or plants. With hybrids you are forced to buy new every year. This is why hybrids are pushed by nurseries and garden centers. Those centers make money from hybrids.
