Answered from the vendors’ own pages

Census (formerly getcensus.com) has been acquired by Fivetran. The domain permanently redirects (301) to fivetran.com. Census functionality is now part of Fivetran's data platform.

Merge: What is a Linked Account in Merge?

A Linked Account represents an end customer's authenticated connection to a third-party application (like Salesforce, HubSpot, or Zendesk). Merge pricing is based on the number of production Linked Accounts your end users activate.

Source
Census: How much does Fivetran (formerly Census) cost?

Fivetran uses usage-based pricing. Free tier includes 500,000 monthly active rows (MAR) for connections, 3,500 MAR for activations, and 5,000 monthly model runs for transformations. Paid pricing depends on usage; example: Facebook Ads with 34,479 MAR costs $17.23/month; Snowflake-to-Salesforce with 12,007 MAR costs $202.01/month.

Source
Merge: Can I access custom data not in Merge's universal schema?

No. Merge works well for standardized integrations but hits limits with enterprise customers. You cannot access data outside Merge's universal schema, cannot customize integration behavior for specific customers, and cannot pull deeply custom data from source systems.

Source
Census: Do Fivetran/Census offer discounts for annual commitments?

Yes, annual contracts offer up to 22% savings versus monthly pricing. Additional discounts are available for nonprofits, startups, and specific use cases.

Source
Merge: What happens if I switch away from Merge?

Merge holds your customers' OAuth tokens. Switching providers means asking every customer to re-authenticate, resulting in potential customer churn and unhappy users.

Merge: Does Merge work with legacy systems?

No. Merge only works if there's an API. Legacy ERPs, government portals, insurance carriers, and older enterprise systems that customers depend on often don't have APIs, making Merge unable to support these integrations.
