Its important to contextualize these discussions in socioeconomics. Computers are not just fun play things. They are serious tools used for economic activities. Their usage, through their design, has significant impact on the social systems of society. Non-latin-language speakers are able to use poorly localized computers, but they are only able to use them less well than the latin-language speakers. At least in South Asia, there is a huge economic divide between those who can speak English and those who can't, where causality runs both ways, and in more recent times exacerbated by the inability of some to use technology. And that economic divide then causes huge sociopolitical problems in societies.
If computers are means for economic progress, we shouldn't put the condition that one has to somehow learn English to use them well. But isn't localization sufficient? No it isn't. Ignore even that localization requires some members of your language to be dual speakers. The current era of economic progress is characterized by software development. But if the only way you can develop software is to learn a foreign language, then surely we are denying economic progress to some communities.
P.S. I will repeat. Nobody has to do any work to help other communities. But to assert that such work should not happen is plain wrong.
