I know this question has been answered similar times but I’d like to post it again since I’m still not 100% sure: What exactly is the difference between:
‘if you continue using our product’ and
‘if you continue to use our product’
For me the difference broadly between gerund and infinitive in this sort of construction when either form can follow certain verbs is - the gerund refers to a general activity whereas the infinitive refers to a specific activity. An example -
If you continue eating certain foods, you will put on weight. General statement based on fact
If you continue to eat masses of chips with every meal, you will more than likely have a heart attack. Specific reference with a hint of threat/warning.
