All eBay promotions are for the benefit of eBay.
They have decided it is in the best interests of eBay and its stockholders (who receive dividends based on eBay's profits) to drop the huge number of listings in favour of increasing the numbers of listings available to Store subscribers and also to sellers without Stores.

The subscription price has not been increased, and subscribers who don't need the increased number can downgrade their Stores at no charge over the next couple of weeks.
Subscriptions give the company a steady income flow, unrelated to whether the sellers are making sales or not.
You do not have any listings so I'm not clear why this is a problem for you.
