Haz, obviously this is your opinion and your entitled to it, however it is based on limited knowledge of your own surrounding areas. Also dont take it personally, but you have ones on here who have been doing this a whole lot longer than yourself with vast experience and knowledge.
Yes wfp makes it easier for people to try their luck and get into this line of work but and its a big BUT, it makes very little difference as this has always been the case and there is more to it than just offering a cheap under cutting price. If this was the case, all of us who have been doing so for longer than 7 yrs would have no business what so ever. Ask any of us if we know of many one man bands in the areas where we work which charge very little for cleaning windows. We can all tell of many which we know and have known over the many years! I know in two villages where I work, that I am double and triple some guys n little groups who can knock out houses really fast ie 3 on a house.
Even UK window cleaning company offers free cleans to coax ones to them and so far I have lost ermmmmmm 0 customers to them.
Yes technology is changing and apps improve but not many will fall for it. Whats the name of that new one, where customers receive gifts and rewards from their window cleaner via this app/group? I dont think that is taking off too great at the moment and i dont think it ever will. Plenty of things can change in ten years, granted but plentybof things wont change ie people want a good reliable services and have spent years prior putting up with false economies and sales gimmicks and so not everyone will search out the cheapest window cleaner or the cheapest thing because they have learnt what in reality the cheapest "whatever" gets them!
So, im also one who has a different opinion.
