From my perspective, I do not think Apple is making their changes in iOS to limit small business in anyway and is having a positive impact in many respects with relation to privacy. I think you can still have privacy and help businesses succeed. Imagine if FB were more privacy conscious (might reduce their annual turn over a little but i dont think detrimentally), worked with apple to product a product and tech that preserved privacy while allowing advertising to continue.

It can happen, FB just doesntt want to for either $$$ or for loss of control.
