Why only 1 Core seat with paid Hubspot but unlimited Core seats with free?

No, but at least you can have these two free users and they can create and manage contacts, even if they keep the Hubspot brand. I understand that they want to grow their profits, but this is a hard blow for companies that are just starting out. At least one would think that they could have paying users and the free ones who could create their own contacts at least. I think Hubspot pushed with this measure. I myself am organizing a migration to another system. For many of my clients who I helped to organize with Hubspot and then always ended up buying, it will no longer be possible because they have to enter with an investment from day 0.
