There is a shitty think called "Card refresh". Big companies can have deals with Credit card companies, because, at the end of the day, both of them need your money.
Lets say, you gave your card automatic monthly billing to company 'X'. You would normally expect that when card expires, it won't be billed anymore and they will ask you for new card details. The reality is company 'X' goes to credit card company and tells them "We have these card details with us. Everything except expiry date is same. So you can conclude that we legitimately obtained the card details. Can you give us the new card details. We will update the account accordingly. It is even useful to the customer as he will be (cough cough) inconvenienced."
I think something similar happened in your case.

I really wish the relationship was inverted. So I had a dashboard of every recurring charge in one list and I could cancel at will. More designed around me pushing funds to vendors than vendors pulling them from me.
Someone should make a digital first credit card optimized for the subscription world.
Had a friend who went back recently. Life outside work is good. Closer to family, all daily chores are taken care of by maids and servants. But w.r.t work, you don't get enough number of quality people. They still need hand holding or "push". Most people are smart but do not know how to deliver end to end.
I think it really takes truck-loads of courage in going back, taking that massive salary-cut. But if one's a family-oriented person, then it makes sense.
This question gets asked for every company. The way it works is that Amazon and Instacart. may copy. But walmart and target will be slow to respond. At some point, Amazon will be ahead in the game and Walmart is in a hurry to bring something similar to buy. Then they will acquire Bottomless
Another way, even if Amazon introduces it, they have to make $x billion from it to be viable. If Bottomless makes $100M per year from this funtionality, they are a good business. Meanwhile they can also rake up a few patents thus making forcing Amazon to pay some fees
