Google isn’t what it used to be, but the free alternatives like DuckDuckGo aren’t really that great. Given how vital a good search engine has been to make any use of the internet since the late 90s, I think it’s not unreasonable to offer quality search at a reasonable price.
I’m not aware of any paid-for search engines, and I’m not sure what they could charge for without seeming greedy. Perhaps have a free tier that limits you to so many searches per day and a paid tier with unlimited searches and another with API access or something. The key would be to have a good-better-best system that makes everyone feel they’re getting a reasonable product for what they’re paying while keeping the experience serviceable for free riders.
Email is similar. While it’s not too hard to set up a bare SMTP server, a bare SMTP server will get you absolutely nowhere because every reputable email service will flag it as spam. The hard part is making the server pass all the sniff tests that other services use. You also cannot self-host because residential ISPs block port 25, again as a spam prevention mechanism.
I pay for Proton, not because I trust them per se, indeed the more a company trumpets about how secure and anonymous they are the more suspicious I get. But I trust them more than I trust Google and that’s what matters.
How is your email not flagged as spam? Last time I ran my own email/domain, I could hardly deliver anything. Been 10-years though and I’ve learned more about best practices. Can it be done now?
I haven’t done it myself but know people who do. If you use a known provider and only the domain is yours I wouldn’t expect it to be blocked as companies also use their own domain for their email.
Running your own SMTP is still going to be tough. But you can use a mail provider that lets you use your own domain, then you can use their SMTP which should not get flagged as easily.
