Gonna call it now: that 60 quid 'one time' purchase is not gonna be the end of it.
In, at most, a couple of years, one of these things will happen:
- the model will be switched to a monthly subscription
- features will be cut and sold separately
- 'limited, non-targeted' ads 'from trusted partners' will be introduced
- the thing will be buried completely because it's not financially viable
