I just told you why Ebay's situation is different. Uber was defrauded and wasn't a failure of advertising. Advertising can be complicated, but part of the value of these giant networks is helping to run those campaigns effectively. I'm not sure why you think everyone has to put in similar amounts of effort. That's not necessary at all. You have tools from simply setting the budget and targeting lookalikes of people liking your posts (what most small businesses do) to running your own bidder stack (for larger brands that have entire agencies working for them). While attribution will never be perfect, it's not guessing either. Ecommerce only makes it easier as you can track all the way from exposure to checkout, and in some ways can be more attributable than other businesses expenses.
