Well. Some people believe bitcoin is money and adding other stuff is "spam" Others see it as a data chain that can do all sorts of "cool things" by making blocks bigger which is better for big business and government.
Core despite extreme controversy removed the ability to cut out "spam" out. You can no longer do that on v30nodess. Their argument wascontradictory sort if stuff I've seen in many fields. Stoppingbspam is "Censorship". Well we always stopped spam and it wasn't censorship then. And so on. Turns out a lot of did vs are fundedb donations from companies whose business model needs a big bitcoin chain.
Core had a monopoly running 99%++ of node SW. So its actually a major vulnerability of BTC
Knots dev got banned from core dev team for arguing...by the guys that were funded by the corporations. He wrote knots which is core pre v28 but enhanced spam filters. Not removed.
He said in a decentralized network users decide.
Since introduction a huge number if " bitcoin ethis" types have started tonruj knots. Its gone from like 0.1% to 20% +
"Core" team responded intially ignoring knots.
"Core" later launched DOS attacks on nodes!!!!!
"Core" also posted that non-economic ie not big business, nodes don't matter.
Bitcoin is decentralized and having a handful of people (Devs) who get most of their money not from their BTV but from "crypto companies" is not good.
If core changes take effect and spam gets added, then the node size willget very big, making running a node on cheap hardware impossible. "Core" says that's good, but cause only "economic" nodes matter.
Its an issue that has split a lot of bitcoin community, broadly down the more "old school decentralized bitcoin/as the new miney" vs "make bitcoin better for gov and big investors, banks, miners and big tech"
You can research the issue for yourself. Me I switch to knots. We need several node options to stop one getting captured by a couple of dodgy like so many other systems have in the world
