This is true, but Porkbun couldn't be further from the big registrars like GoDaddy in their approach. It is actually difficult to buy a domain on GoDaddy for most people without getting sucked in to buying extras, whereas Porkbun barely even suggests extras at any point since I've been a user, and what are extras other places are offered for free.

Pretty much. Everyone wants to upsell you on their hosting, page creation and blogging tools where they have ridiculous margins. How much disk space and bandwidth do you think a random small business or Jane Rando's recipe blog actually use vs. what they're being charged for? Not to mention things like "brand protection" where they'll do you a solid and buy/squat your domain on the .xxx and .sucks tlds for extra $$ each month.
