Does 1 review make or break a company? I've been seeing a lot of "5 star vs 1 star" issues recently. One of them was on an Uber article where the customers were not getting 5 start for not tipping for example and this impacted their ability to get rides (or so I think based on what I read). A lot of other smaller companies selling stuff online only and even Indi games seems to be very sensitive about reviews. Is the difference between overall 4 star vs 5 star so impactful? Maybe there is a deeper problem somewhere in here. Or maybe this is a reasonable backfire for a bad customer support.
