While online reviews of products help you to form a general opinion, I believe they're not the best source to judge a PROFIT MAKING company. A lot of successful brands such as Dominos, Royal Enfield etc have their share of criticism on the internet but they proved to be great businesses to own in the past decade. While the concerns raised by the blogger maybe genuine, I believe interacting with actual customers would give us a better understanding of the product & company.
Views maybe biased.
