Why did you think they would extend the updates? The day Pixel 4A was announced the said they would have only updates till August 2023 and they did honour the guarantee and now your disappointed they didn’t update beyond their guarantee. https://support.google.com/pixelphone/answer/4457705?hl=en

To my understanding Tesla has higher short interest because it trades at 58 x 2024 estimated earnings. Meanwhile S&P 500 is around ~18x. Also Tesla only has 2-3% short interest, it is only high when you compare it against other automakers but when you compare it against their P/E ratio you will understand why that is the case.
