they should feel ashamed
I am a user with accessibility and vision-related limitations who relies heavily on voice dictation software because excessive visual strain can worsen my condition. What happened with your software during the writing of my 42-chapter manuscript was deeply distressing. The document appeared to save correctly, yet recovery versions were incomplete, and repeated upgrade and read-only prompts created confusion about what had actually been saved. For a disabled user, this is not a minor annoyance. It creates genuine fear of losing important work and places extra strain on people who already face barriers using technology. Someone with more severe accessibility limitations than mine could easily lose years of work because of these practices. I believe the way WPS Office handles saving, recovery, upgrade prompts, and document restrictions is unethical and harmful to users. Software that people trust with important creative work should never create uncertainty about whether their documents are truly safe. You should be ashamed that your product design creates this kind of stress and risk for accessibility users and writers who depend on reliable saving behaviour.
