Conclusion I've had for some time is:

There are low-end "budget" scopes intended for little kids who don't know anything about telescopes, have no idea collimation might be desirable let alone be capable of doing it. They will be happy if they actually manage to point it at something and get any image out of it. In addition there's a high likelihood they'll pull it apart and it won't be quite the same again afterwards.

These same users will also probably give it half a dozen sessions before they lose interest and dad puts it under the house to be quietly forgotten and eventually tossed out.

That's why these scopes are built of of the cheapest possible materials, have no adjustments, and are designed for a user about 1 metre tall to use on a table.

There are also larger versions of same for bigger kids, particularly some 10"-16" dobs that also aren't built to survive more than a dozen nights out and have only the most rudimentary adjustments, and are mechanically very flimsy.

This is nothing new; low end junk telescopes have been around for decades. Not for nothing was Tasco also known as Trashco.
