Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.
There is this interesting question about how much product and marketing and vibes and lore correlate. Did we forgive Sierra On-Line the numerous flaws of their games because we liked the company? Do we love Panic because we like what they do, or because of how they do it? Did Google put doodles on its homepage to distract people from more nefarious things, or because it just felt like a fun way to celebrate things? Is there such a thing as pure selflessness? What is the nature of free will?
