If you add up all the services you get, the premium membership is a steal. For example, you’ll notice they include unlimited keyword research with a membership. Other paid keyword research tools sell for $49 or more just by themselves. Add in website hosting, and there’s another $10 / mo. Add on the website security package, and there’s another $10 per month (I’ve paid as much as $29 / mo just for website security). Just based on those things alone, Wealthy Affiliate is a great deal with all of the resources and tools you need in one convenient place. Not to mention all of the training, tutorials, and support that is included with the membership.
Wirecutter's affiliate program might make you doubt the legitimacy of Wirecutter's recommendations -- but, in fact, it's quite the opposite. Wirecutter only makes commission when a reader purchases a product from an affiliate retailer and doesn't return the product. Wirecutter, then, has no incentive to promote inferior products -- if they did, they'd make less money and turn away readers.
