@alicelthwaite Hey Alice, thanks for your question! I guess the main difference would be the reward or incentive. The quality of the feedback or the time you dedicate to try the product when you do it for free or you have an incentive it's really different. :)
Of course there are tech lovers giving great feedback every day, but let's say you need the feedback of a lawyer (I will not generalise, but this profession, at least in Spain, is still well behind digital transformation). That would not be so easy without an incentive!
