In the interests of transparent disclosure on such a positive blog post, It might be worth calling out that all the links on the page are all linked to the Bunny Affiliate Program. [1]
Yeah IANAL, but this sort of endorsement with undisclosed remuneration would probably run afoul of FTC guidelines, which is why you see disclaimers like "As an Amazon Associate I earn from qualifying purchases" everywhere. The author seems to live in the UK, but a cursory search suggests there's something similar there as well.
Sorry, I realize I overdid it on the affiliate links so I've called out the link and removed some others. Just thought it was nice that they had an affiliate program. Nothing shady intended!
