From the book:
The emigrant and sportsman in Canada. Some experiences of an old country settler.
By John Rowan, 1876

On still summer nights, when the tide suits, lobster-spearing parties are the fashion among the Halifax people. A birch-bark torch, carried in the bow of the boat, enables the spearer to see the lobsters crawling about among the seaweed at the bottom. In those bays, where lobsters are really plentiful, I have seen two hundred taken in one tide by a couple of little boys, wading about among the rocks, armed with cod-hooks tied on to sticks.
On one occasion, after a heavy gale in New Brunswick, which threw up tons of lobsters on the beach, I saw several acres of potato ground manured with them. To give some idea of the little value put upon lobsters by the country people, I may mention that on some parts of the coast they boil them for their pigs, but are ashamed to be seen eating lobsters themselves. Lobster shells about a house are looked upon as signs of poverty and degradation.

Probably because insect-food will be heavily processed (with all the downsides that brings) whereas things like grass-fed cow is more organic.

So the parasites (food and pharma industrial complex) want plebs too eat ze bugs while only the wealthy can afford ze real superfoods.

For me, part of the negative perception is that it feels like it's being pushed by a political organization, based on faulty premises, rather than growing naturally out of consumer preferences.

I see no problem with people choosing to do it...
