ELI5: What is wrong with genetically engineered crops?

What do people have against GE crops? I can't seem to find anything online about the problem with them, mostly it's just people saying stuff like "There is no evidence that they are bad", but if that's true, what do people have against them?

There are some people who argue that GM crops are bad for the environment. This is false.

There are some people who argue that GM crops are bad for the health of people who eat them. This is undoubtedly true in some cases, but as of yet there's no solid evidence that it's more true than of any other kind of food. (There's no solid evidence *against* that either.)

There are some people who argue that, even if there's nothing inherently wrong with GM crops, the companies who promote them act unethically. This is the most convincing argument against GM crops, because... well, the corporations involved with them *do* act unethically sometimes. People can disagree on interpretation, but unlike the other two issues, nobody disagrees with the GM opponents on their basic facts.
