"Risk management" means different things for individual investors and
joint-stock business firms.  For individual investors, there is a
tradeoff between risk and return.  They can and should accept a lower
return in order to reduce risk.

Firms exist to shoulder risk.  They don't want to take unnecessary
risk, but (in theory at least) it is desirable that a firm minimize
risk only within constraint of maximizing profit.  The reason is that
if the firm trades off return for lower risk, the individual
investor's ability to diversify is blunted.

So, if in fact the firm's management judges that there is some "best
project in its field", then in that field they should choose to invest
in that project only.

Correctly so, in my expert opinion.  Merely opinion, I don't know of
any "theorems" here, but definitely informed by expert judgment.

High risk, low ROI should be avoided at all cost.  This just doesn't
make sense, either from a pure economic standpoint (firms should
engage in high risk, high ROI projects) or from an institutional
("management for the managers") point of view, where risk should be
minimized to protect the managers's salaries and privileges.

So you think that the managers of Red Hat and IBM are just stoopid?

Did I see you write "IBM" and "can't afford to do *much*" in
succeeding sentences?

Doesn't it make sense to fix the management problem that allows
"momentum" to take over, rather than locking in a guaranteed low
return?  Don't you realize that a department whose mission is to
distribute $X/N to N prepurchases, and must devote managerial
resources to liaison with each of the prepurchase vendors, is likely
to gain a certain amount of momentum in each of those prepurchases,

You're ignoring the monitoring expenses, which will be substantially
higher than for an internal project (or equivalently result in
substantially poorer information), and will increase more than
proportionally in N.  You're also ignoring the expenses of enforcing
the prepurchase contract (eg, where the buyer thinks they're buying an
impending major release but a minor release is delivered with a major
release number and the developer claims the contract is fulfilled).

Of course you can get rid of both monitoring and enforcement expense
by simply acknowledging that you're not talking about "pre-purchase,"
you're talking about patronage.

I really don't think so.  If the competitors were going to be on an
even footing, they'd have to be big.  That's expensive, and not
"continuously adjustable".  Worse, a lot of what Eclipse is about is
the open architecture.  IBM would simply have sponsored a Blu-Ray
vs. HDD battle, to everyone's detriment.  Nobody in their right mind
does that.
