If any this sounds like a propaganda move aimed at giving the people a feeling that the government has done something about it.
Some of these may relaunched as a web service, some may relaunch under a different branding, there are any number of things the app makers can legitimately do to skirt around this.
Using summary executive powers to do such is a rather undemocratic move, and which time and again this Indian Government has indicated it has no qualms of using.
This is a politically motivated move, where as it should not be. If there was established wrongdoing then ban the apps, not because it is politically convenient to do it.
