The part I’m really blown away by is that I just saw this final project in the intro to design class I teach from a group of international students earlier this spring. The project was to create a logo design and brand guidelines as a small team. The students can pick the business and whether it’s new or a rebrand, and this group went with social media all-in-one apps and made the justification that they are hugely popular in China, but nothing like that exists in the US. My favorite part is that the letter X was a HUGE part of the logo/branding, but they did not name it just “X” specifically for the reasons you listed - it’s not discoverable or unique in searches, the App Store, etc.
