I've had multiple "big companies" leak my randomly generated email addresses. I create a unique one for each such account, like say my airline frequent flyer account for delta, and I've had several of those leak.

They won't do anything. Had this exact scenario with two Shopify-based sites where my address somehow ended up with the second shop. Reported it, shop 1 investigated themselves and found themselves to be innocent, case closed.
