It would be great if any&#x2F;all of these developers&#x2F;companies can guarantee the app will be around for X days &#x2F; years after the user <i>buys</i> it. Then it&#x27;s a contract and you wont feel bad&#x2F;betrayed once the app is gone (acquisition&#x2F;bankrupt etc)<p>They can always end of life it after their last sale.<p>This guarantees the user that it&#x27;s worth the time&#x2F;investment, and the company can always decide to prolong the contract &#x2F; expiration date.<p>Software (Best if used by X&#x2F;XX&#x2F;XXXX)
