Tasteless strawberries are around for a few reasons
1) you can't try before you buy. bigger, redder strawberries look better, so sell better, so are grown more, and so on until that's the expectation. if varieties are cultivated for their looks, that means they're not cultivated for their taste or sugar content
2) bigger strawberries are easier/faster to pick, which means they're cheaper to pick
3) people want strawberries in winter, which means for a lot of us that means we're accustomed to buying strawberries that have been shipped thousands of miles and not picked recently.
