> If for some reason your mail server is flagged by Gmail's systems, then it only won't reach Gmail users.

This is a deal breaker for most people and organizations. Not being able to send email to the largest email provider is orders of magnitude more important than upholding some values about decentralization and independence.

Sure, but that's a problem with that provider, not with the service or protocol.

If you're not allowed to shop at Walmart, that might be an inconvenience, but it doesn't stop you from shopping anywhere else. That is the point of decentralized protocols. They prevent a single entity from creating a monopoly over the entire market. It's not just a philosophical argument about independence.

Besides, even Gmail obeys standard email features like DKIM, DMARC and SPF. As long as your server is not on the same network as known spammers, and doesn't have the usual spam signals, there is little chance that your emails will be blocked.

But if Walmart has a monopoly over certain goods, it is more than an inconvenience to be banned from Walmart. If your email server cannot deliver mail to 25% of all active email addresses, that's more than an inconvenience.

We can quibble about semantics, but those examples are not caused by centralization.

Yes, any company can take advantage of their position to influence the market, and in most cases this is illegal.

If a manufacturer only offers their products in Walmart, and some users can't access Walmart, then that's a problem specific to that provider and manufacturer. And the same applies for Gmail. *This is not because decentralized protocols "trend" towards centralization.* It is because there will always be popular providers that people gravitate towards for whatever reason. But again, this doesn't prevent anyone from using email without depending on Google _at all_.

The difference from that situation and issues caused by actual centralization is night and day. I'll stop replying to this kind of rebuttal, since it seems people struggle to understand the difference.

Eh, I would phrase it differently -- decentralized protocols ensure that new competition can stand up services.

There's nothing about them that inherently prevents monopolies from forming, as this thread discusses re:Gmail. Usually there are enough value adds around the decentralized protocol that a smart first mover can establish a de facto monopoly.
