The main disadvantage of an electronic government is to move the government services into an electronic based system. This system loses the person to person interaction which is valued by a lot of people in today's society.
Also there are some opponents of e-government that argue that online governmental transparency is suspicious because it is maintained by the governments themselves. The Information can be added or removed from the public eyes. this day, very few organizations provide accountability for these modifications. Even the governments themselves do not always keep track of the information they insert and delete
and the implementation of an e-government service is that, with many technology based services, it is often easy to make the excuse" the server has gone down" that problems with the service provided are because of the technology
Possibility of data theft, malware, phishing etc., i.e. all computer related problems. A good cyber security plan can prevent this.
Lack of e-literacy. This is more relevant to Indian context where apart from people even some government officials show this lack. This problem is temporary and can be solved through skill development and making people literate as well as e-literate.
If e-governance is not properly implemented, it can make the life of the computer-illiterate citizens more difficult, particularly if alternative previous ways of solving the problem have been withdrawn.
E-governance may lead to privacy issues. There is a risk of private data of citizens getting stolen. There is also a possibility of rogue government employees misusing private data. Encryption and security therefore become very important. Thus, there is added cost of training the government employees and/or hiring highly skilled professionals.
Digitization results in ease of access of data, which is a double-edged sword. The government sometimes can pass legislations undesirable to citizens without adequate information of the citizens, and then go on to use the easily-accessible data for its purpose.
E-governance also results in job losses, and many low-rung jobs getting replaced by a few high-rung jobs. This is disadvantageous for those who lose jobs.
Overall, though, e-governance is the way of the future, and future can't be prevented from happening. Thus, strictly speaking, the above are challenges, not disadvantages.
The disadvantages of electronic - government. The main disadvantage concerning e-government is the lack of equality in public access to the internet, reliability of information on the web, and hidden agenads of government groups that could influence and bias public opinions.
