Founder of the biggest UK platform here (also active in Germany and US). Influencers have been talked down for the whole four years we’ve been active. Don’t forget what we’re comparing this to. Banner ads! Instagram influencers who are thoughtful and authentic are great. If you don’t like it you can unfollow the influencer. Same cannot be said of banner ads where the end user has little control and you get chased bet…
If your main focus is slinging products, I don't see how that equates to being thoughtful or authentic; especially, when your end-goal is just chasing the next few quid.
For example, I'd expect Neill DeGrasse Tyson's IG to be far more thoughtful and authentic than, say, Amanda Strand's IG.
