I agree that it is not really that much profitable on the free spins, I personally do not really get much from them neither. It's fine though, in the end we are talking about something that is dangerous in the long run because if you rely on them then you will most likely already lost the normal way as well.

We should only focus on the regular gambling we do and nothing more, if we keep doing that then it would be a lot better and it would give us a good result for sure. Doesn't mean that we shouldn't realize regular gambling will make us lose too, but it would be quite boring and would be definitely useless if we keep thinking that house edge will get us all the time.
