Twitter CEO Parag Agrawal was no understatement when he warned his employees about "distractions" and "noise" a few days ago.

He could also have spoken of a nightmare.

Because his new major shareholder Elon Musk, who would actually have enough to do as CEO of Tesla and SpaceX, has now unsolicited made a purchase offer to Twitter - and with that a horror scenario for the company becomes true.

Musk has been chasing it for days, and now he's throwing it into a hostile takeover battle.

Exactly what drives Musk in this saga is unclear.

In any case, it doesn't seem to be just financial motives.

Perhaps the sheer desire to provoke plays a role.

He himself describes his commitment as a fight against censorship and for democracy, he argues that Twitter curtails freedom of expression.

However, it is doubtful whether he, as one of the biggest rowdy makers on the platform, is able to judge this soberly.

Crossshots from an erratic major shareholder

It is also questionable how seriously he means the purchase attempt at all.

The "best and final" offer he made is by no means generous, and he's likely to be rebuffed for now.

He might even withdraw offended.

In any case, with his advance he made Twitter a pawn in the financial markets.

There the question is now asked whether other prospective buyers could also be found.

All of this comes at a bad time for Twitter CEO Agrawal.

He only took up his post a few months ago, and his task is difficult enough as it is.

For years, Twitter has failed to realize its full potential.

There's a curious disparity between the company's massive presence in public discourse and its manageable economic size, compared, say, to Facebook.

Agrawal wants to change that and has set ambitious goals for the next few years.

Now he has to deal with cross-shots from an erratic new major shareholder.
