What about updates on codecanyon (envato) and technical support after the expiration date?

Question

Business Informatics

Hello.
Question to users who have been on envato and his daughter codecanyon for a long time.
There is a license and support. Standard for six months, extended for a year. But what will happen a year later? https://yadi.sk/i/qBFNyDj53HSZXG - for clarity.
1. For example, I took annual support, a year has passed - is there an update and will I receive it? those. will receive updates 2, 5 years?
2. All the same, a year has passed since the purchase. I need the support of the author - what should I do in this case? Where to extend it? Or I will have to buy the product again and for $11.63 take a year of support - for a total of $46.63. But in this case, I don't need the product itself. I have it and it works. But we need separate support after a year, two, five.
Or is there no such thing as a product (option) as a lifetime support? And I bought a product - it is yours for a year and support is provided for it, and then buy the whole package again?
3. I understand that in 30 years of sales (hypothetically) on envato (with such lifetime support) the author will accumulate such a base of active customers that he will not be able to support everyone (or he will have fun in retirement). Therefore, tell me where it is written on the code that the author is not obliged to support them until the end of his days.
I will be glad to answer three points with links to these rules on envato or codecanyon.
Question for knowledgeable users who have encountered such a need and questions. Thank you.

Answer 1

1. Updates are free regardless of the caliper. Just in case of problems after the update, it will not work to contact the support.
2. Buy more support. In the place where the price is right now, there will be a button "XX months of support left. Renew?". If it ran out: "Your support has ended. Renew?". Support will cost 11.63
- sorry, not 11.63 - this is the promotional amount, if you take it right away. After the expiration date, it will be more expensive. Example:
I answer 1 and 2 based on my experience (I have been buying on envato for more than 3 years).
3. If the author sells on envato for 30 years and he has such a huge customer base with a paid techpod, it is unlikely that it will be 1 person. There is a whole team for this.
