Why are almost all frozen berries as sour as all get out?

I don't really understand that sentence, but I find almost all
supermarket fruits to sour. Especially berries, peaches, apricots,
nectarines, plums often too.

Most ripe fruit, especially berries, won't hold up well during
shipping so they're harvested while still green.
However berries for freezing typically don't need to be shipped, they
are frozen in the field, so they would be picked fully ripened. For
processed crops like frozen and canned the factory is transported to
the fields in large semi trailers. If frozen fruit is sour it's time
to change brands.

The raspberries we once grew ourselves were much sweeter than the
frozen ones I can buy. Maybe it was a nicer type.

When it comes to fruit, I only buy fresh mangos and lychees anymore.
There, sourness never seems to be a problem. But never peaches or
nectarines.

I live in a fruit belt. I can get fresh raspberries, strawberries,
blueberries, rhubarb, sweet cherries, sour cherries, peaches and more
fresh from farms within a few miles of home. Fresh local produce is
always much better than imported fruit. I love mangoes, but it is next
to impossible to get a nice ripe one here, or even to get one to ripen
evenly. I have pretty well given up and now buy them frozen. The frozen
mangoes may not compare well to the fresh locally grown that you can
get, but they are better than the mangoes I can buy, and not waste.

We have farmers' markets, but they're quite a drive away. Mangoes are
everywhere in the season. We even had the first ones from our own 2
trees just a few weeks ago. Passion fruit, citrus, banana, pineapple,
blueberries also do well here. It's too warm for cherries and the more
common types of apple.

I didn't bother mentioning apples and pears because they are not as
perishable as the tender fruits. I have to say that I am envious of
anyone who can get fresh mango.

Yep. This is why I don't like fruit.

This maybe applies to fresh fruit in your case. In such a case, I do not
mind tartness at all.

But to get back to frozen fruit, I have noticed that if it is in the fridge
freezer compartment (not in the 'deep' freezer), oftimes the citric &
ascorbic acids will react to form tartric acid.

It is especially noticiable with frozen concentrated cranberry juice. If
the supply chain operators have not been diligent about keeping it
deep-frozen, it only takes a few weeks for a pink sludge to develop.

If you do not like the tart taste, it ends up tasting better because much
of the soluble tart acids (ascorbic & citric) have been precipitated into
insoluble tartric acid sediments. But the texture is a bit unpleasant.
