You may be correct about WAAS but ADS-B is available now via voluntary fitment (the NFRM was yonks ago) and if you fit to GA (if you can find a system to fit) you can fly VFR without Airservices making a cent.
Profit? Airservices is a Government
owned corporation.
However, do you see anyone in private enterprise rushing in to provide WAAS, XM WX, TIS etc? I doubt I'd be purchasing shares based on their prospective profits
