I’d pay more money for an option without the endless phone calls and emails, it’s like advertising that you have to listen to.

Multiple cookie cutter options + "call us if you want" works pretty well for Salesforce. Pay-for-what-you-use-until-you're-huge is sufficiently profitable for AWS/google cloud/Azure. The frustration expressed here is against the companies that force prospective users to call them, no matter what.

Having tiered pricing + "Call us if ..." works at a large scale. At small scale, particularly smaller startups in the B2B space, extracting value from each deal matters a lot more as you don't have anywhere near the level of deal flow on your inbound funnel.

Note that B2C is totally different and unless you're doing some very high priced / bespoke delivery then you have to go cookie cutter.
