It’s just the global market trend to blame for this, not any single author per say. One or the other company would do this, so you either get on board and take advantage of it or not and loose on this income stream.
Besides unlimited downloads markets and regular markets customers tend to not overlap too much, since they are mostly different customers, looking for different things.
One type of customer is looking for lots of content and is willing to start a subscription, those things which you can easily forget to cancel… and the same customer is mostly willing to pay 200$+ dollars for a yearly subscription just to get a “deal”.
Another type of customer is one who needs only one track at a time, and they aren’t willing to start subscriptions and don’t want to pay $200+ upfront just to get a “deal” and they would rather spend $29 on a single track.
All of this is according to this year’s Envato conferences data.
I personally enjoy the best of both worlds, by being on regular market and elements. I would say elements is a great earnings opportunity and would encourage you to get onboard and take advantage of it, instead of fighting market trends.
