Early government support of R&D and market support is one of the things that Germany (and a few other countries) contributed to the current success of renewables.

So that is in part why they are cheap, but they are also simply cheaper now due to their scale of production.

Nothing 'absurd' about that though so not quite sure what you're claiming is happening. Presumably something along the lines of there being a big conspiracy to hide the true costs of renewables which hurts the real cheap energy sources, which are fossil fuels. Which feels backwards to me.

No, they are currently not subsidized at all. What was done was guaranteeing minimum prices for renewable energy. These prices used to be way higher than market prices to make renewable energy generation economically feasible. This way especially important in the first decade of this century and back then you could call the renewables heavily subsidized.

But recently market prices for electricity were by far exceeding the minimum guaranteed prices, so you can't call those renewables as "heavily subsidized".
