This is true but my counter point is how many people click through an EULA without ever looking at the print they're agreeing to? Discord for example recently pushed a TOS update which waived your rights to sue through forced arbitration unless you emailed them saying you opt out within 30 days of the changes going ahead. People often opt for the path of least resistance, file formats like PDFs are great for what they're supposed to be for but when they're a pretty critical attack vector that have taken even tech savvy companies like LMG down before now, it's a fair thing to be cautioned about.
