That text can be translated is not an advantage, images can't be translated because they don't need to. The twitter image is expensive to store but also contains a different kind of information, that would be very hard to convey over text with the same precision and accuracy - how does one describe it pixel by pixel? I could go on - I agree with the idea but text is only king when text is the best tool, or you have the mind to fill the gaps (like in a novel) and you don't mind variance between readers, or the data is high structure but low resolution like concepts. Images are high resolution and it's important to recall them exactly, with perfect accuracy, thus they require a lot of information. Plus I'm not sure the best storage was used for that icon. Text also compresses very well, so it must not be quite the densest. Like I said, I could go on.
