Not just that. From my personal experience, twitter had to be one of the slowest websites I use. Even in my 2020 mac, it often shows the memory warning in safari. Things take a while to load. And the UX is terrible with having to constantly click to read child comments, having to click on “show hidden replies” etc. I honestly have no idea how a company with thousands of employees and a billion in loss was able to operate such a terribly performing website.
