Mastodon is financed by crowdfunding instead of venture capital not because we don't know that venture capital exists, not because we don't have bills to pay, and not because venture capital isn't willing to give money to new social media platforms. VCs don't want a sustainable business, they want a big exit. Every VC-backed business is on a timer to deliver or die.
Stop pretending it's about "#crowdfunding", for you. You are expressly working on bringing #advertising to the #Fediverse, and the Mastodon instance that you run.
