Difference between differents sales

Hi, when I do a researche of ENFOLD THEME to google, there is a long list of provider of this theme, like the following:
https://pluginwp.net/en/producto/enfold-responsive-multi-purpose-theme/
https://www.etsy.com/es/listing/1890185624/tema-multiproposito-responsivo-enfold
But when I check your page:

You redirect to the follow page:
https://themeforest.net/item/enfold-responsive-multipurpose-theme/4519990?irgwc=1&clickid=0zk32HyqZxyKUhp3KYRHO1-gUkpwClz0N0aR3k0&iradid=275988&irpid=1236844&iradtype=ONLINE_TRACKING_LINK&irmptype=mediapartner&mp_value1=&utm_campaign=af_impact_radius_1236844&utm_medium=affiliate&utm_source=impact_radius

Can you let me know the difference between buy your pluguin from themeforest instead from https://pluginwp.net or https://www.etsy.com ?
Maybe the difference is:
With themeforest updates are live time.
With https://pluginwp.net or https://www.etsy.com to get updates I need suscribe to them every year?
Waiting for your reply.
Best regards.
