How American Users’ Platform Conservatism Fuels Monopoly - and why That’s Dangerous

In the U.S., the online classifieds market has long been dominated by a handful of major players: Craigslist, Facebook Marketplace, eBay. These platforms set the rules, impose restrictions, filter content, and decide which links are allowed - and which are not.

But few talk about the fact that it’s user behavior - their conservatism and loyalty to “legacy” platforms - that makes this monopoly possible.

Habit Over Logic

American users have been using the same platforms for decades:

• Craigslist - since 1995

• eBay - since 1995

• Facebook Marketplace - since 2016

Even if the interface is outdated, moderation is strict, and the rules are opaque - people keep using these services. Why?

• Habit: “Everyone sells here - so I will too.”

• Fear of change: “What if the new platform isn’t trustworthy?”

• Social pressure: “If I don’t post on Facebook, no one will see it.”

What This Creates: Behavioral Monopoly

When millions of people use the same platforms, they:

• reinforce their market power

• normalize their algorithms

• accept any restrictions as “standard”

And in the end - platforms dictate the rules, not users.

Users can’t:

• freely post links

• promote their own websites

• use UTM tracking

• analyze performance

• optimize listings for SEO

Why This Is Dangerous

• Freedom of publication disappears

• Small projects can’t compete

• Algorithms decide who gets seen

• Platforms become gatekeepers, not tools

And all of this — because users aren’t willing to try something new.

What Can Be Changed

Independent platforms are emerging - like bobseller.com, where:

• you can post listings without restrictions

• external links are allowed

• no algorithmic suppression

• moderation is transparent and ethical

• the interface supports SEO and analytics

But for these platforms to become viable alternatives — users need courage.

The American online classifieds market suffers not only from algorithms, but from user passivity.

As long as people keep using the same platforms “out of habit,” they’re actively supporting a monopoly that limits their freedom.

It’s time to shift the mindset:

• try new platforms

• support independent projects

• set the rules — instead of obeying them

Platforms should serve people - not the other way around.
