Tweetbot is a paid app. Its revenue model wouldn't be fundamentally affected by Twitter putting ads in the feeds it displays.

I'd rather see ads in my feed than Twitter continue to make third-party clients less useful.

Or Twitter could share the ad profits a la YouTube to incentivise all kinds of innovative niche ui's. 3rd parties are not the enemy to be managed. They are a blessing - free engineers who managed the impossible of building a product with customers and traction. UI is a cost for Twitter.
