It can be, and it's a valid point. But some countries do publicly fund their government broadcaster and have safeguards in place to maintain journalistic integrity. It can be done properly.
Australia is one: https://about.abc.net.au/who-we-are/the-abc-board/. The ABC regularly has fact checking articles for politicians on all sides and has exposed many a government scandal over the years.
Except voting day in Australia is on a weekend, not during the week. And there are also pre polling centres, where if you plan to be away on vacation or working on voting day, you can go along to a pre poll centre and vote weeks in advance. Australia also has mail in and even telephone voting for those unable to visit these centres.
